Struct std::alloc::AllocError

source · [−]

pub struct AllocError;

🔬 This is a nightly-only experimental API. (allocator_api #32838)

Expand description

The AllocError error indicates an allocation failure that may be due to resource exhaustion or to something wrong when combining the given input arguments with this allocator.
